SPECIFICATION forming part of Letters Patent No. 426,793, dated April 29, 1890.

Application filed July 6, 1889. Serial No. 316,724. (No model.)

To all whom it may concern:

Be it known that I, JAMES H. FOOTE, a citizen of the United States, residing at Cincinnati,in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in lVindow-Sashes; and I do declare the following to be a full, clear, and exact description of the invention, reference being had to the accompanying drawings, which form a part of this specification.

This invention relates to those windowsashes which can be raised and lowered within vertical grooves of aframe or casing or turned on a pair of pivots, so as to be either horizontal or inclined at any desired angle; and the first part of my improvement consists in the provision of a spring which normally tends to hold a hollow guide in engagement with a groove of the sash. This spring may be fitted either within the guide and adapted to bear against the sash-cord fastener, or it may be located within the case of the pivot mechanism; but in either event its duty is to temporarily couple the guide to the sash, so as to compel the latter to travel in a vertical path, as hereinafter more fully described.

The second part of my improvements comprises a novel push-pin which is fitted to the pivot-case and can be readily advanced by a persons thumb for the purpose of forcing the hollow guide into the frame-groove, and thereby supporting the sash wholly upon its pivotbearings, in order that said sash may be conveniently turned, as hereinafter more fully described.

The third part of my improvements com sash, said sash being arranged to be raised and lowered with the hollow guide. Fig. 2 is a horizontal section of said bearing taken at the line Y Y. Fig. 3 is another section ized side elevat-ion,but showing the sash supported by the pivot, so as to be turned thereon. Fig. 4 is a horizontal section thereof, taken at the line Z Z. Fig. 5 is a front elevation of the face-plate of the case that contains the pivot mechanism. Fig. '6 is an enlarged transverse section of the push-pin.

Figs. 7 and 8 are two different modifications of the spring arrangement.

A represents a portion of a box window frame or casing, and a, is a vertical groove therein, which groove is traversed by a hollow three-sided guide B, that is preferably made of sheet metal and is usually as long as is the sash to which it is applied. This hollow guide has near its mid-length a vertical slot 1), through which passes a lug 0, projecting horizontally from the end of a short cylindrical barrel D, whose periphery is grooved or fluted longitudinally, as at d. This barrel is adapted to slide freely within a cylindrical neck 6 of the edge plate E of a case F, within which theprincipal operative parts are housed in the manner shown. The outer or face plate Gof this case has a cylindrical bearing 9 for a reciprocating push-pin H, which is chambered out, as seen in Figs. 2 and 6, and has an oblique end h, adapted to press against the barrel D. The opposite end of this chambered push-pin is also closed and is traversed by a pivot c of a head I, that may be milled or roughened to enable apersons thumb to bear against it more effectually.

Loosely coupled to the inner end of the pivot 1' is a latch J, the advancing edge of which is beveled off, as seen at j in Fig. 6, in order that said latch may readily ride over the notches I; 70' of a bar or plate K, secured within the case F.

L is a lifter rigidly secured to the pivot 'i and adapted to raise the latch J when the head I is properly turned. Z is a spring that retains said latch in its normal or closed position. I

Push-pin H is grooved longitudinallyon its upper and lower sides, as seen at h h", which grooves admit guides M M, secured to the top and bottom plates of the case, by which arrangement this pin is confined to a proper path and is preventedturnin g within the cylindrical bearing g. Face-plate G is slotted horizontally at g for the passage of the rounded portion 01 of a swinging catch N, suitably pivoted to the rear of said plate, the free end of this catch being adapted to enter either one of the grooves (Z of barrel D. The pivot scribed, after which act the head I is turned of this catch has a pair of flat facets, against so as to lift the latch J out of the notch 7c, either one of which the spring a bears, and and thus liberate the push-pin II. The stress 70 thus holds said catch either in or out of gear of spring R now drives the guide B into the with the aforesaid barrel. Faceplate G is groove 0 and advances the push-pin II until secured by screws g to the sash O, the latter its latch re-engages with the first notch 7t, being grooved vertically at o to admit a porand then all the parts are again in their nortion of the guide B. mal positions. 75 Pis a sash-cord fastener sliding freely with- The above is a description of the preferred in said guide and having a socket p to admit form. of my invention; but if the construethe lug C of barrel D, the cord or chain Q, bction of the window-frame is such as to prein g attached to said fastener in any suitable vent the use of the spring within the framemanncr, but preferably as shown. groove the expedient seen in Fig. 7 may be 80 R is a spring secured at its center to the adopted.

In the other modification (seen in groove 0 until it comes in contact with the Fig. 8) the barrel is traversed by a k0 3, edge plate E of case F, as seen in Figs. 1 and whose notch s engages over a rib or flange 1) o 2, and the lug 0, being engaged with the of the sash-cord fastener, and is held in consocket 79, couples the sash O to said fastener, tact with said rib by a spring T.
